To understand how Yellow Submarine came to be, one first has to appreciate that this film NEVER HAD A FINISHED SCRIPT. Instead, the artists worked with fragments of multiple scripts by numerous authors (over 40 according to Erich Segal), combined with the input of the Animation Directors, Key Animators, Animators, Background Artists, and anyone else who had a good idea. Although it gave me, and probably many of you, the impression of a coherent, purposeful story loaded with hidden meanings and possible symbolic interpretations, this landmark film literally evolved as it was co-created, and is the combined input of dozens of multi-talented artists.
